Husband works at a rock quarry and car washes just don’t get his undercarriage clean. This worked perfectly. Super easy to attach to the power washer and very easy to use. Highly recommend.
I've used both the Water Broom and the Undercarriage Washer. 1st - Water Broom. I cleaned the salt from my garage floor. The broom lifted and pushed the salt easily. It is better than just a pressure washer single nozzle because there is less fan-out with the broom . The water and salt is pushed in front of the broom instead of fanning out with a single nozzle. 2nd - Undercarriage Washer. After seeing how well the broom cleaned, I was concerned that the undercarriage washer might have so much pressure that it would damage something under my car and van. Too much pressure is not a concern because when rotated to wash the undercarriage the washer throws a lot of water but not at a high pressure. I was able to put my hand in the water stream without injury. In my opinion the undercarriage washer is perfect for my vehicles - lots of water at low to medium pressure.
I bought this as a gift for my husband. Living in the country, we are constantly trying to keep gravel and dust from getting tracked into the house. This attachment is easy to assemble and perfect for cleaning the driveway and garage floors. Even better, it can clean the under-carriage of our vehicles to reduce how much dirt comes into the garage on our vehicles too.
